Vibration is a key factor of abrasion and destruction in the internal combustion engine. In internal combustion engines, the main causes of vibration is combustion pressure, connecting rod weight, piston weight and inertial forces. This vibration create corrosion and fracture in main part of engine such as crankshaft, camshaft and cylinder block in long time. This corrosion and fracture is effe...

Nowadays, increased attention has been focused on internal combustion engine fuels. Regarding environmental effects of internal combustion engines particularly as sources of pollution and depletion of fossil fuels, compressed natural gas has been introduced as an alternative to gasoline and diesel fuels in many applications. A high research octane number which allows combustion at higher co...

In the modern world, one of the largest concerns is the ever depleting supply of oil. The automotive industry is especially impacted. In recent years the price of gasoline has fluctuated substantially and the price of crude oil has reached record highs. The high price of gasoline coupled with the uncertainty of its availability and future price have put a high priority on fuel economy of an eng...
